MOVING-PICTURE MACHINE.

Specification of Letters Patent.

Application filed August 14, 1917, Serial No. 186,104. Renewed December 81, 1818. Serial No. 269,178.

- To all whom it may concern:

Be it known that 1, JOHN H. STILLWaG- son, a citizen'of .the United States, residing at Richmond Hill, in the county of Queens, city and State of New York, have invented an Improvement in Moving-Picture Machines, of which the following is a specification.

Heretofore in the operation of moving picture machines as commonly constructed, it is necessary to place a reel of film in the machine, and in the operation of the apparatus by suitable mechanism, this film is unwound from the reel, passed over an optical center, travels with an intermittent motion and is wound on another reel. After the reel is thus run off, it is necessary to rewind the film on to the first reel from the second reel after the reels have been removed from the machine in order to have the film ready for're-use. In the interval between removing and placing the film reels in the machine, it is customary in some instances to project slides of any suitable nature, showing advertisements or pictures upon the screen, and in other instances to employ a --plurality of machines used alternately so that the moving picture performance is continuous.

The various operations of changing and rewinding the reels at the present time are performed manually, and the object of my invention is the provision of a moving picture apparatus in which these various operations are performed automatically, and in carrying out the same I prefer to employ a film actuating mechanism which is mounted upon a reciprocating carriage normally 7 maintained in an initial inoperative position, means for moving the carriage so that the film is moved into and out of an operative osition. I also rovide means for automatically starting t e film actuating mechanism after the carriage is moved into its operative position and for automatically reversing and rewinding the film after the carria e is moved out of and has been returne to its initial position. As will be understood, the period in which the film carria e remains inits initial position may be on y sufiicient to rewind the film, or it may be any reater length of time, as is desired,.and w liile this interval may he 0verned by any suitable mechanism, I emp 0y,

as shown and described in the present machine, a device operated "by an endless conveyer for this .purpose. This endless conveyer preferably carries a plurality of slides which are successively projected on the screen during the interval in which the film is being rewound and the slides thus displayed may be of an advertising or pictorial nature, as desired. When it is not desired to display slides my invention comprises an apparatus in which there is a battery of machines adapted to be successively operated to show the roll of film in each machine in turn. In this form of the invention when one roll of film is unwound it automatically starts the second machine, and its movement is reversed so as to rewind, and when rewound is stopped, and this is repeated until the rolls in each machine are shown.

From the foregoing, it will therefore be seen that in the use of the form of my improved moving picture as herein shown and des :ribed, appropriate slides are successively thrown on the screen and at redetermined intervals a reel of moving plctures is displayed on the screen, the film carriage for which, being moved automatically into place without change of lenses, and immediately after the moving picture reel is run off, the reel carriage is automatically returned to its initial position and the slides again displayed sucoessively while' the film is being rewound, and these operations are continu-' one so long as the electric circuits controlling the apparatus are closed.

The moving 'ioture apparatus herein shown and descri ed is particularly adapted for advertising purposes, as for example, to illustrate the manner in which a given article is manufactured, but the use of the a paratus is not so limited, because it will go apparent that it may be applied for amusement, entertainment or educational purposes to equal advantage.

In the form of the invention which I have herein illustrated, I employ a frame comprising suitable side members 20, 21, preferably of similar construction and secured to one another by a plurality of spacer and connecting rods 22, to the opposite ends of which are secured nuts 23 to hold the parts together. A motor 24 is mounted with its base 25 on a bracket 26 secured in any desired manner to the frame of the machine. One end of the motor shaft 27 is connected to one end of a drive shaft 28, the opposite end of which is journaled in a bearing 29 fixed in the frame of the machine. On the drive shaft 28 is a worm 30, meshing with which is a gear wheel 31 mounted on a'shaft 32 which extends between and is journaled in the sidemembers of the frame of the machine. On the shaft 32 is a pinion 33. This pinion 33 meshes with a, gear wheel 34 mounted on a shaft 35, which also extends between and is journaled in the side members of the frame of the machine. On one side of the gear wheel 34 there is a broken circular flange 36 and a pin 37, these members forming parts of a well known intermittent movement, the other member of which is a cam wheel 39 mounted on a shaft 40 whichalso extends between and is suit? ably journaied in the side members of the machine. The curved surfaces 41 of the cam wheel 39 register with the surface of the flange 36 and between each curved surface 41 there is a radial slot 4% adapted to receive the pin 37, so that by the revolution of the gear wheel 34, the cam wheel 39 and shaft 40 are intermittently turned a partial revolution.

On the shaft 40 there are sprocket wheels 43 and journaled in the side members of the machine and preferably immediately above the shaft 40 is a similar shaft 44, mounted on which there is a pair of sprockets 45. At the other end of the machine there is a shaft 46 corresponding to the shaft 44 and on this shaft there is mounted a air of sprockets 47. Beneath the shaft 46 t ere is a shaft 48 on which there is mounted a pair of sprockets 49. Passing over the sprockets 43, 45, 47 and 49, are chains 50 which perform the function of endless conveyors for the slide plates hereinafter described. In suitably spaced positions slide plate frames 51 are connected at their opposite sides in the links of the chains 50, and each slide plate frame 51 is adapted to receive and carry a slide plate indicated at 52. The chains 50, during that portion of their travel in which the slide plates are carried along their upper horizontal positions, pass through guides 53 in order to insure the slides being maintained in their proper positions for projecting the design on each slide properly on to a screen, and as will be understood, the relation of the parts is such that while the travel of the endless conveyer chains 50 is continued, the slide plates are successively brought into osition to be projected on the screen. his, as illustrated in the drawing, is preferably a central position lengthwise of the apparatus.

For projecting the slides on the screen, I have illustrated the use of an electric lamp bulb 54, suitably secured in the socket 5.5 mounted in the frame of the machine, and also a condenser 56 secured in osition in the frame between the lamp bu b and the stationary operative position of a slide, as well as a lens mounted immediately above the lamp bulb and condenser by means of a plate 58 extendin across the side members of the machine an secured in posts 59 which are suitabl attached to the side members of the mac line. This portion of the apparatus, as will be recognized, is an ordinary stereopticon structure in which the slides are caused to move intermittently and by this intermittent movement are successively brought into position to be projected on the screen. This latter however forms no art of m invention and is not illustrate y I a so employ a film carriage adapted to be reciprocated transversely o the machine so as to bring the film into the optical center of the projecting'device of the ap aratus. This film carriage preferably comprises side rails 60 and 61 connected to one another in spaced positions by the tie-rods 62 and 63. This carriage is mounted to reciprocate on thespacer rods 64 and 65, which with other similar rods secure the side members 20 and 21 of the frame together. On the spacer rod 64 there are collars 66, and in similar'positions on the spacer rod 65 there are collars 67, these collars being employed to deter mine and limit the travel of the film Cal's riage. Also 'conn'ected'to the film carriage are bearin "plates 68, 69; these are secured to one ano er in spaced positions by. means of the tie rods 70 and 71, and these bearing plates preferably are ribbed on their outer.

sides while the inner sides of the rails 60 and 61 are recessed to receive the ribs on the bearing plates, as clearly indicated in Figs. 3 and 8 of the drawing. Associated with the film carriage is an auxiliary bearing plate 72,

which as indicated, is secured in position exteriorly of the side rail 60 by means of tie bolts 73, 74, or otherwise.

The mechanism hereinafter described as associated with the film carriage, is driven by a motor 75, the base 76 of which is mounted on the bracket 77 suitably secured in the frame of the machine. On the shaft of the motor there is a pulley 78. A spring belt 79 asses over the pulley 78 and also over a pul ey 80 mounted on a shaft 81, which is journaled in the auxiliary bearing plate 72 and in the bearin plate 68. On the shaft 81 there is a gear wieel 82. The gear wheel 82 meshes with the gear wheel 83 mounted on a. shaft 84 which is journaled in the bearing plates 68 and 69 and also in the auxiliary bearingplate 72. Similarly on the other side of the apparatus, the gear wheel 82 meshes with the gear 85 mounted on the shaft 86, which is journaled in the bearing plates 68, 69 and the auxiliary bearing plate 72.. On the shaft 84 there is also secured a gear wheel .87 which meshes with a gear wheel 88 mounted on a shaft 89, the shaft '89 being journaled in the bearing plates 68, 69, and-the auxiliary bearing plate 72. Corresponding with these last named gears on the other side of the apparatus, a gear 90 is mounted on the shaft 86 and meshes with the gear wheel 91 mounted .on a shaft 92 which is journaled in the bearing plates 68, 69, and the auxiliary bearing plate 72.

On the shaft 84, a disk 93 is mounted. This dish 93 is provided with a broken flange 94, and a pin 95 on the same side thereof. Adjacent the disk 94 there is a cam wheel 96 mounted on the shaft 97 which is journaled in the bearing plates 68, 69. The curved surfaces 98 of the cam wheel 96 are adapted to engage the surface of the flange 94 and betweeneach curved surface of the cam wheel, there is a slot 99 adapted to be entered by the pin 95 so that through the revolution of the disk, intermittent motion is imparted by the cam to the shaft 97. On the shaft 97 in spaced positions there are film sprockets 100 coacting with grooved rollers 101 mounted on a shaft 102 which is 106 monnted'on .a shaft 107, the ends of which are 'ournaled in the bearing lates 68 and 69. T e curved surfaces 108 o the cam wheel 106 bear against the surface of the flange 104 and between the curved surfaces of the cam Wheel there are slots 109 adapted to be entered by the pin 105 so that through the revolution of the disk 103, intermittent motion is imparted to the shaft 107 upon which the cam wheel 106 is mounted. On the shaft 107 there are spaced fiim sprockets 110 coacting with grooved rollers 111 mounted on a shaft 112 which is journaled at its ends in the bearing plates 68 and 69.

On the shaft 89 and. in line with the film sprockets 100 there are film sprockets 113 coacting with ooved rollers 11-1 secured on a shaft 115, the ends of which are 'ournaled in the bearing plates 68 and 69. 1 imilarly on the other side of the machine and in 'line with the film sprockets 110 there are film sprockets 116 mounted on the shaft 92 and coacting with grooved rollers 117 secured on a shaft 118 the ends of which are also journaled in the bearing plates" 68 and 69.

At one end of the machine the film carriage is provided with brackets 119 in which there is journaled a shaft 120 which extends across the film carriage. Centrally this shaft 120 is provided with a collar 121 held frictionally in contact therewith by any suitable means so as to turn thereon if sufficient turning force is exerted to overcome the frictional contact, and one end of the film indicated at 38 is suitably secured to this collar 121. At one end of the shaft 120, a sprocket 122 is fixed, while in line therewith on the shaft 89 there is a similar sprocket 123. A chain 124 passes over the sprockets 122 and 123, so that the shaft 120 is driven from th shaft 89 and through the sprockets 122, 123, and chain 124. Associated with this shaft 120 is a reel case 125 having a cover 126 which is preferably hinged thereto as indicatedjat 127. On the opposite end of the film carriage there is a similar construction, brackets 128 being secured to this end of the film carriage and having mounted therein a shaft 129. On this shaft 129 there is a collar 130 similar in all respects to the collar 121 on the shaft 120. Also on the shaft 129 there is a sprocket 131 and in'line therewith on the shaft 92, a. similar sprocket 132. A chain 133 passes over the sprockets 13-1 and 132 so as to turn the shaft 130 from the shaft 92. With the shaft 130 there is also associated a reel case 13 providud; with a cover 135 which is preferably hinged thereto as indicated at 136.

A strip of film which is indicated at 38- is passed through uide members 137, plainly indicated in F1 10, and over guide rolls 138 and 139. e film then passes over the guide surfaces 140, 141 provided therefor on the shafts 84 and 86 and under the film sprockets 100 and 110 andbetween the same and the coacting rollers 101 and 111 respectively. The film is then looped as P181111 indicated in Fig. 5 and passes around the under side of the film sprockets 113 and 116 and the ved rollers 142 and 144 coacting therewit The rollers 142 are mounted on a shaft 143 journaied in the bearing plates 68, 69, while the rollers 144 are mounted on a shaft 145 also iournaled in the bearing plates 68, 69. The film at the opposite sides of the film. sprockets 113 and 116 passes over the rollers 114 and 117 respectivei and throu h idlers 146 and 147, which will be hereina ter more particularly described, and thence into the reel cases 125 and 134, passin between idlers 148 and 149 provided there or respectively in these reel cases, where the respective ends of the film are suitably secured to the collars 121 and 130.

Secured in a suitable position in the frame of the film carriage there is a bracket 150. A shaft 151 is journaled in this bracket and provided with a gear 152 meshing with. the gear 91 and also on the shaft 151 is a beveled gear 153 meshinig with the beveled gear 154 mounted on the shaft 155 at right angles to the shaft 151 and suitably secured to which is a diaphragm 156. The diaphragm is provided with suitable openings rmitting the light to pass through the lm when the motion thereof is arrested, as is customary in moving picture'machines. Also suitably secured in position in th film carriage is an auxiliary lens 157 and an auxiliary condenser 158 coacting therewith, the auxiliary condenser being supported upon depending arms 158' connected to the film carriage.

Associated with the film carriage I provide an auxiliary contact carriage adapted to be reciprocated longitudinal y thereof.

.This auxiliary contact carriage preferably comprises rods 159 and 160 mounted above the frame of the film carriage. At corre sponding ends thereof blocks 163 are secured to the rods 159, 160 and a cross bar 164 extends between the blocks 163. Simi larly at the opposite ends of the rods 159 and 160 there are blocks 165 secured thereto, and. a cross bar 166 extends between the blocks 165 and is suitably connected there with. The idlers'146 are journaled at their ends in the blocks 163 and the idlers 147 to which reference has hereinbefore' been made-are journaled at their ends in the blocks 165. The rod 159 at one end thereof extends appreciabl beyond the'block 163 securedthereto an is provided with a helical sprang surrounding this extending end of the and extending between the block 163 and ahead 168 provided thereon, and as indicated in Fig. 2 of the drawing. On this end of the rod 159 there is an an le bracket 169 carrying a depending arm 1 0 adapted to actuate a switch 171 employed in controlling the circuits to the motor 75 which drives the film actuatin mechanism, this switch being supported m a suitable strap 172 secured to the film carriage or otherwise, and the construction and operation of this switch will be hereinafter more particularly described.

I also employ a housing 173 secured to the side frame member 21 of the machine for inclosin a switch 174 for the control of the circuits for 0 rating the machine. This switch preferabl; includes a contact 175 and the terminal 176, the contact 177 and its terminal 178 together with a contact arm 179 and its terminal 180, the housing being provided with an aperture 181 through which a pin 182 extends when the film carriage is suitably moved so as to strike the contact arm 179 and move the same from the position shown in Fig. 11 to a position in which at its free end it bears against the contact 177, and as will be hereinafter more particularly described. For controlling the circuits to properly 0perate the mechanism, I also employ a rotary switch mounted on a shaft 35 so as to turn therewith and provided with contacts 184 and 185 having the respective terminals 186 and 187.

In older to effect the reci rocating movement of the film carriage and the parts asso ciated therewith, I employ a cam 188. This as particularly shown in Figs. 4, 5, 6, 8, and 9, is a channel iron of angular shape in plan, and is secured to the under side 0 the film carriage by suitable posts depending therefrom and indicated at 189'. Gooperating with this cam 188, I employ a roller 189 adapted to revolve on a pm 190 suitably secured in one of the slide plate frames 51, as is clearly indicated in Figs. 8 and 9 of the drawings." The slide plate frame carrying the pin 190 and the roller 189 is not provided with a slide in order to permit the light unobstructed to pass through the frame in projecting a icture from the moving film, and as will e apparent, when the slide plate frame carrying the roller 189 a proaches the center of the machine, the rol or will enter the channel in the cam and the continued movement of the slide plate frame by the endless conveyer chain carrying the same, will cause the film carriage and arts associated therewith to move from air initial position, as shown in Fig. 2 of the drawing, to

1 iwwaul m the position shown in Figs. 8 and 9, in which as will be understood, the film guide with the film between the same and the auxiliary lens 157 and condenser 158 will be brought into the optical center of the projecting apparatus of the machine, and

. nected b as hereinafter described, these parts will remain in this position so long as the moving picture film is being operated.

eferring again' to the switch 171, the same preferabl includes a plate 191 adapted to be oscil ated, and carrying contact arms 192, 193, 194"and-195. The contact arm '192 is adapted to bear against the contact point 196 or the contact point 197 suitably fixed in the base of the switch. The contact arm 193 is adapted to bear against either one of the contact points 198 or 199 fixed in the base of the switch, while the contact arms 194 and 195 are adapted to bear against, the contact points 200 and 201 to be removed therefrom The plate191 also includes an arm 202 provided with a slot 203 adapted to receive the end of the depending arm 170 so that through the movement of the auxiliary contact carriage the switch 171 may be thrown from one to the other of its positions, as will be hereinafter more particularly ex lained.

Referring to Fig. 14 of t e drawing, electrical circuits for operatin the hereinbefore described apparatus inclufie the lead wires 204 and 205, the former of which is connected to one terminal 206 of the'motor 75 for actuating the film mechanism while the opposite terminal 207 of this motor is cona lead wire 208 to the terminal 178 of t e contact 177 of the switch 174, while the other lead wire 205 is connected by a line 209 to the terminal 180 of-the contact 179 of the switch 174; One terminal of the motor 24 for actuating the slide operating mechanism isconnected by a line 210 to the lead wire 204 and the circuit is completed to the motor 24 in three ways first by the line 211 connecting the opposite terminal of the motor with the terminal 176 of the contact 175, thence throu h the contact 179 through the line 209, a so through a line 212 extending betweenthe line 211 and the contact 185 of the rotary switch 183, through the switch and the other contact 84, by the line 213 to the terminal 180 of the switch 174 and the line 209, and in the third instance through the line 214 extending between the line 211 and the contact point 200 through which when the switch 191 is'in the proper position the circuit will be completed through the contact arm 194, the line 215, the line 216' to the terminal 180 of the switch 174 and the lead line 218 with the contact arm 192 and the contact point 197 is connected by a line 219 to a line 220, which line is connected to one of the commutator terminals of this motor. A line 221 connects the contact 70 point 196 with the other commutator terminal of the motor which is also connected by a line 222 with the contact point 199, while the contact point 198 is connected by a line 223 to the line 220 and the contact arm 193 is connected by a line 224 with the other field terminal of the motor.

In the operation of the hereinbefore de scribed apparatus, the film carriage and associated parts are normally in the initial position indicated in Figs. 2 and 3 of the drawing, and the switches for controlling the currents for operating the mechanism are normally in the position shown in Fig. 14 of the drawing. ow by closing the circuit by a switch in the lead "wires 204 and 205, it will be a parent that this circuit will be closed throng the motor 24 for actuating the operatin mechanism this circuit being from the lead 204 through the line 210, mo tor 24, the line 211 the contact 179, its terminal 180, and the line 209 to the other lead wire 205. The slide actuating mechanism will therefore continue to operate, throwing each successive slide upon a screen until the slide frame carryin the roller 189 approaches the center 0 the machine, and as will be understood, the designs on the slides are progected successively on the screen. As this sli e late frame approaches the central position, t e roller 189 enters the groove in the cam 188 and moves the film carriage and associated arts from the position shown in Figs. 2 a '3 to the position shown in Figs.

8 and 9, in which the roller 189 is at the apex of the channel in thg cam and the film carriage has been moved to the extreme limit of its travel in which the auxiliary lens and the auxiliary condenser are brought into position to cooperate with the main lens 57 and 119 the main condenser 56 to project a picture carried by the film onto the screen. As the film carriage is brought into this position, the pin 182 extends through the aperture 181 in the housing 173, moving the contact arm 179 from the position shown in Fig. 11, in which this bears against the contact 175 to the o posite position in which it bears against t e contact 177. When the contact 179 is moved to this osition, thecircuit through the motor 24 is broken at the contact 179, but is still closed through the rotary contact 183. At this time also the 'circuit is closed to the motor 75 for actuating the film actuating mechanism.- The motor 75 therefore turns and through the mechanism hereinbefore described, operates the film, unwinding the same from the reel case 134 and into the reel case 125, the circuit through the motor 75 being closed from the lead wire 204 to the terminal 206' through the lead 218 to the contact arm 192 throu h the lead 219 to the line 220, to and throng the armature of the motor to the lead 222, to the contact arm 193 to the lead 224, to the o osite. field terminal of the motor, thence to t e opposite terminal 207 of the motor, and by the lead 208 to the contact 177, contact 179 and the lead 209 to the opposite lead wire 205. The apparatus will continue in this operation un til the film is nearly played from the reel case 134 and into the reel case 125, or until a trip 225 laced on the film adjacent the end thereo passes between the idlers 149 and strikes the idlers 147. v When this etc 225 strikes these idlers, it "moves the auxi iary contact carriage through the continuin motion of the film and by the movement 0 this carriage through the action of the spring 167, the dependin arm 170 is moved from left to right as in lcated in Fig. 4 of the drawing, thereb swinging the plate 191 of the switch 171 rom the position shown in full lines, Fig. 14, to the position shown in dotted lines therein. In this position,

.the current through the motor 75 is reversed by passing through the lead 218 to the contact arm 192 to the contact point 196 through the lead 221 to one armature terminal, from the other armature terminal through the lead 220, the lead 223 to the contact point 198, through the contact arm 193, the lead 224, the other-field terminal, through the field, and to the other motor terminal, and by way of the lead 208 to the contact 177, to the contact 179, the lead 209 to the other lead wire 205. In this position also the circuit is closed to the motor 24 through the lead 214, the contact arm 194 the lead 215, the lead 216, to the terminal 180, the lead 209 to; the opposite lead wire 205. This as will be understood causes the endless conveyer to be set in motion again which in turn through the pin 182 and the-other side of the cam 188 returns the film carriage and the parts associated therewith to their normal initial position. It will also be understood that as soon as the pin 182 is withdrawn from the intimated, my invention includes an apparahousing, the contact 179 returns to its normal position against the contact 175. This ordinarily would break the circuit through the motor 75, were it not for the fact that t e contact arm 195 is in a position to bear against the contact 201 so that the circuit through the motor 75 is still closed through the lead 208, the contact 177, the lead 217, the contact am 195, the lead 216, the contact 180, through thelead wire 209. This condition maintains with the slide mechanism in operation to display the slides successively when the film is being rewound from the film case 125 to the film case 134, until the initial position of the film is reached, that is to say, until the film is rewound in the case 184 so as to be ready for use again.

apparatus normally When the film is so rewound, the trip 226 fixed on the o posite end of the film, passes between the i lers 148 and comes into contact with the idlers 146 on the auxiliary contact carriage. This as will be understood,

operates the carriage in the opposite direc-;

tion, whereby correspondingly moving the arm 170 and throwing the switch 171 back to the full lines position shown in Fig. 14. This opens the circuit to the motor 75, so that the film actuatin mechanism remains inoperative until the m carriage is moved again as described, to cause the pin 182 to move the contact 179 so as to close the circuit to the motor 75, in which position as will be understood, the operation of the machine is repeated. The purpose .of employing the rotary switch 183 is to continue the operation of the motor 24 and the movement of the slide apparatus until such a time after the film apparatus has been started, as to bring the parts of the stop motion for the slide mechanism into such a position that the pin 37 is about ready to enter one of the slots 42, the reason for this being that in a ain starting the slide mechanism, it is deslrable to have the film carriage and its mechanism moved out of the way, so that the picture on the film will not be displayed in its reverse order on the screen. \Vith the parts in this position, return movement of the film carriage to its initial position begins immediately upon the starting of the slidecarrying mechanism.

The a paratus hcreinbefore shown and describe has proved satisfactory in all respects for an advertising machine. It may be necessary however in o crating moving ictures for theaters to Slllfl. the slide pro- ;ecting lens 57 out of position when the movmg picture projecting apparatus is moved tus in which a plurality of film reels are employed in pairs together with a film movin mechanism associated with each air of rec s and in which each pair of ree s and their corresponding film moving mechanism may be automatically moved from aninitial'inoperative positlon to an operative position and then actuated and automatically returned from the operative position to an inoperative position, and the film rewound automatically.
